Genus Tegotettix Hancock, 1913

Tegotettix: Hancock 1913 , Günther 1937, 1938, 1955, Blackith 1992, Yin et al. 1996, Otte 1997.

Type species: Tegotettix armatus Hancock, 1913 .

Composition and distribution. Nine species inhabiting Cambodia ( T. bufocrocodil ), Thailand ( T. bufocrocodil ), Borneo ( T. armatus , T. cristiferus , T. siebersi ), Sulawesi ( T. celebensis , T. tuberculatus ), the Philippines ( T. corniculatus , T. sagittarius ) and New Guinea ( T. novaeguineae ).

Notes. The genus is composed of at least a few species groups that are different in morphology and can be easily distinguished ( Günther, 1955). The first group, resembling Gavialidium , is composed of species with strong pronotal projections ( T. armatus , T. bufocrocodil , T. celebensis , T. siebersi and T. tuberculatus ), the other groups is composed of the species from the Philippines without pronotal projections ( T. corniculatus and T. sagittarius ), the third group of one Bornean species ( T. cristiferus ), and one of a single New Guinean species ( T. novaeguineae ). Type species of the genus is Bornean Tegotettix armatus Hancock, 1913 , the species having the highest projections of all the congeners. Species that are morphologically similar to the type species are T. celebensis Günther, 1937 from Sulawesi, and T. bufocrocodil ( Storozhenko & Dawwrueng, 2015) comb. nov. (new combination of Gavialidium bufocrocodil , see Figure 22–25 in Storozhenko & Dawwrueng, 2015), having high fastigial horns, wide shoulders with tuberculated metalateral plate, ventrolateral projection without an apical spine, visible frontomedial projection (small), larger promedial, large metamedial and mediolateral projections, triangular infrascapular area, not widened hind tibiae, and strongly dentate fore and mid femora and fore and mid tibiae. Members of this genus do not have ventrolateral projection produced in spine, but with truncated margin. The genus is in need of revision.
